DNS is the phonebook of the internet, turning domain names into IP addresses. Your ISP's default DNS is often slow and logs your queries. A reputable public resolver is usually faster, more reliable and more privacy-respecting — and it's free to switch.
Popular public DNS servers
The most trusted free resolvers are easy to remember:
- •Cloudflare — 1.1.1.1 and 1.0.0.1, focused on speed and privacy.
- •Google Public DNS — 8.8.8.8 and 8.8.4.4, fast and globally reliable.
How to change DNS by device
On Windows, edit the adapter's IPv4 properties. On macOS, use System Settings > Network > DNS. On iPhone and Android, set DNS in Wi-Fi settings or a private-DNS field.
DNS vs VPN
Changing DNS is quick and free but doesn't encrypt your traffic. For real privacy and more consistent connectivity, pair it with — or replace it by — a VPN, or your own private server.
DNS FAQ
Does changing DNS make the internet faster?
It can speed up how quickly sites resolve, though it won't increase your raw bandwidth.
Is public DNS safe?
Reputable resolvers like Cloudflare and Google are safe and have clear privacy policies.
Do I need a VPN if I change DNS?
DNS alone doesn't encrypt traffic — a VPN or your own server is still best for privacy and a secure connection.
